'He's a real trooper': Puppy dragged behind a truck for more than a mile making 'amazing' recovery after horrific injuries

A five and a half-month-old puppy dragged for more than a mile across a Missouri interstate is expected to survive while described now wagging his tail nearly nonstop.

Now named Trooper, the golden pit bull once bandaged from his ears down to his toes, is recuperating under close watch today after his harrowing rescue off a St Louis interstate late last month.

Wearing a leash and a collar, the dog was tied to the back of a truck whose driver took off unknowing that the small animal, whom he had never seen before, was attached, dragging him the entire way.

It was only after another vehicle alerted the truck's driver that he discovered the small dog - with the driver’s reaction described as entirely mortified by police.

Seen today with two leg casts, a raw right ear and a soft knit jersey made for a baby over his body for warmth, his injuries are largely improved having first appeared with exposed tissue and bone and doctors unsure if he'd survive.
